摘要
西南某成品油管道是云南省“五网”建设的重要部分,能够缓解成品油对铁路运输的长期依赖,改善滇东南地区成品油运力紧张局面。目前管道运行工艺的允许回掺能力低,大量混油需在特定站点集中处理,导致站内蒸馏设施处理负荷过高。针对西南某成品油管道运行特性,建立管道瞬态仿真模型,模拟管道顺序输送工况,研究管道混油下载回掺工艺,开展混油掺混实验,提出混油下载回掺方案。管道仿真计算结果表明G站为混油最优下载站点,混油掺混实验结果表明G站的最优下载量能够实现完全回掺。利用提出的混油下载回掺方案,能够缓解下载站点运行负荷,提升混油允许回掺比例,为成品油管道顺序输送工艺研究提供工程依据。
A refined oil pipeline in Southwest China is an important component of Yunnan Province's“Five Networks”project,which can reduce the long-term dependence of refined oil on railway transportation and enhance the transportation capacity of refined oil in southeastern Yunnan.Under the current operating process,the allowable blending capacity of the pipeline is insufficient,necessitating centralized processing at specific station for large amount of mixed oil,which imposes a heavy load on on-site distillation facilities.To address the pipeline's operating characteristics,a transient model was developed to simulate the sequential transportation conditions.The study examines the mixed-oil withdrawal(draw-off)and blending process and conducts blending tests to propose a mixed-oil withdrawal and blending scheme.The simulation results indicate station G as the optimal withdrawal(draw-off)station.The blending experiment results show that the optimal withdrawal volume at station G enables full reblending of the withdrawn oil into the blending stream.The proposed scheme for mixed-oil withdrawal and blending can alleviate the loading at withdrawal stations and improve the allowable blending capacity of the pipeline,providing engineering reference for sequential transportation technology of the refined oil pipeline.
